Printing Plate

3. Lithographic Printing Plate (3) CTP Plate

Abstract

Computer-to-plate technology embraced by today's printing industry for its productivity and profitability benefits represents the next logical step in the transition to an all-degital work-flow. The development of CTP plate has been progressed by all plate makers using either technology based on silver halide, electrophotograghy, high-speed photopolymer, negative type thermal-polymer and positive type thermal-polymer. Fundamental information of the above CTP plates will be described with the general structure, mechanism of image formation, process of image formation and performance.
